摘要:
A series of cheap and easily accessible heteroarylidenemalonate-derived bis(oxazoline) ligands 1 and 2 were synthesized and their copper(II) complexes were applied to the catalytic Friedel-Crafts reaction between indoles and diethyl alkylidenemalonates, Excellent asymmetric enantioselectivities were afforded for the S-enantiomer (up to > 99% ee) in isobutyl alcohol, and the R-enantiomer (up to 96.5% ee) in dichloromethane.
